You will need lots of disposable diapers for this game, but if make sure your guests aren’t too crazy with them while playing the mommy-to-be can use them after the shower (she’ll need tons soon so she will appreciate it).
Give each player a large amount of diapers and a table to work on. Set a timer for 3 minutes and have your guests stack the diapers as high as they can in the time allowed without the stack falling over. If their tower of diapers falls and they have enough time they can keep trying to stack. The tallest diaper tower standing at the end of the time wins. We’ve measured tallest in the number of diapers stacked so there is no need for a ruler, but it can also be tallest measured with a measuring tape (which could get funny as people try to stack the diapers sideways for more height!).
Tip: For large groups you can have your guests play in teams, or in turns, this will cut down on the diapers you need to buy. Have 5 or 6 people playing at a time, while others cheer them on. Then just write down the highest stacking diapers each turn and the tallest diaper tower after everyone has gone is the winner.
It’s really a simple game idea with a lot of options to get creative. You could add to the rules that each player must top their stack with a bottle, or a binkie, or have players stack other multiple objects in as a requirement (such as: 1 rattle, 1 bib, and 1 pair of baby socks). Any way you play you will have tons of laughs watching these “Tower of Babbles” being built… and more fun watching them fall down!
